The next generation of Power Conversion Systems Enabled

by SiC Power Devices is now a reality. As the global trends

promote greener energy with more strict regulations and

standards, newer and more efficient switching devices such

as Silicon Carbide (SiC) devices are gaining acceptance in

various markets from transportation to solar industries.

Compared to silicon devices, SiC devices switching

can exceed several 100’s of kHz, offering substantial

improvements in efficiency. SiC devices also provide

enhanced power density and higher operating temperature,

making them a very attractive alternative to bigger and less

efficient silicon family of devices. As the overall footprint

of inverters with SiC devices shrink, the cooling aspect of

the system becomes a new challenge. Mersen has been

preparing for this challenge and has developed embedded

heat-pipe heat sinks to extract concentrated heat from

areas under the SiC devices and to disperse that heat over

a larger surface area before the heat is passed on to the

ambient environment.

Mersen’s patented Swaged Fins technology is a glue-less,

metal on metal fabrication process to affix fins to heatsink

base plate, providing a final product that can withstand

much higher temperatures compared

to conventional bonded or glued

fin heats sinks. As SiC devices can

operate at much higher switching

frequencies, parasitic inductance and

“skin effect” phenomena become

crucial considerations for bus bar

designs. Mersen engineering teams

can work closely with customers to

design bus bars to compensate for

“skin effect” and to build the most

efficiently cooled power bus bar

solution.

When it comes to protection of

SiC devices against electrical

overcurrents, the most effective

means is the high speed

semiconductor protection fuse (SPF).

SPF has a significantly faster clearing

time to prevent catastrophic

semiconductor device failure.

If you are ready to switch to SiC

devices, Mersen is the right partner

for your cooling, bus bars and

electrical protection.
